vF ig. box constructed according to my invention.

In my present invention, I provide a lire box comprising a forwardly located imperforate coking table, an intermediately posi- 'tioned grate, and a rear dead table, providing a fuel and labor saving lire box. The ire box is especially adapted to be used in burning bituminous coal whichv in the use of my invention, is placed on the coking table fromwhich the smoke, gases, and otherk products of combustion pass over the fire upon the intermediately positioned grate. This insures the fuel upon the coking table being thoroughly coked. In cleaning the 2, is a'verticalsectional view of a lire` upon the grates isi pushed. on the'imperfo- NQv-ixiaijeit@ Y i grates, which is often VVnzcessary,"theyfire-1 f Be it known that '-I, *MATTFL Swanson,` a' citizen of the UnitedStates, and; 'ayre'si'- f dent' of Streator, in the' county. of La? -Salle 60 and State of Illinois, Yhave invented certain#v i dead table is drawn upon-the gratesrandref.. :i Y1' newed by shoving the cckefrcm.thecoking` i Y table with the lire over the grates, prlovidfl inga free burning fire without in any way, having lowered the temperature of"`the kiln.1f

edge being heldl behind the guide flange 15,

which also gives support to thelower edge of the upper fuel door 13, the upper edge` betweenthe flanges 0 and e is the impen-` forate coking table T.

This coking table T extends from one side wall 2, to the other, as shown in Fig. I. Resting upon the extension of the base plate 18 is the grate G, of any approved construction, which has its rear end resting upon the table base 2O upon the top of the base 5. Held upon this table base 2O is the dead table D, made of any non-combustible material as fire brick or the like, as is the coking table T.

As shown in F ig. 2, the forward arch 7 extends backward to a point approximately midlength of the grate G while the rear or similar arch S extends from a point approximately central to the grate and ends at a point approximately central to the dead table D.

As shown in Fig. l, the width of the coking table T is greater than the width of the grates Gvwhilethe dead table D has the lateral wings or ends (Z, these wings CZ extending laterally between the lire bag et and the kiln wall 6.'

In the use of a re box constructed according to my invention, there is no waste o-f fuel or heat and the furnace further can be economically fired.

In cleaning the grates, the partly con; sumed fuel is placed upon the dead table in the manner explained.

The products of combustion further, escaping from the coking table pass through and over the flames of the fire upon the grates insuring a perfect combustion.

As the coking table is imperforate, there is no loss of fuel during the coking operation. The fire box further is simple and inexpensive in construction, and both durable and eflicient in operation, and the grates which are the parts apt to become clogged, may be cleaned with ease, accuracy, and despatch.

Having thus described my said invention, what I claim as new and desire to secure by U. S. Letters Patent is 1. A smoke consuming fire box for kilns comprising a front wall, two side walls, and a top, having an arched ceiling divided into a forward and a rear portion, said front wall having a fuel opening and an ash pit opening, a fire bag being located in spaced relation to the inner ends of said side walls and reaching to said top to provide laterally extending side iiues, a pier extending from said fire bag inwardly from one side wall to the other, a portion of said pier also extending outward between said side walls and fire bag, a table base upon said pier, and the lateral extensions thereof, a dead table upon said table base, the width of said dead table being less than the width of said table base to provide a supporting edge, a base plate located within the forward portion of said fire box having a rearwardly extending supporting edge, a coking table upon said base plate, and av grate supf ported upon said edges, the rear arched ceilingof said furnace being of a radius less than that of said forward ceiling portion to crowd the heat as it escapes out of the fire box.

2; A smoke consuming fire box for kilns comprising a front wall, a top, two side walls, and a lire bag arranged in spaced relation to the ends of said side walls and reaching to said top, the ceiling of said top being arched and divided into two portions, a forward and a rear arch, a pier extending from said fire bag inwardly from one side wall to the other and having ends located between the ends of said side walls and said fire bag, a dead table upon said pier, a coking table located within the forward portion of said furnace, and a grate which is intermediate of said coking table and said dead table the upper surfaces of said tables and grate being in a common plane, said rear arched ceiling portion being of a radius less than that of the forward portion to crowd the heatl as it escapes from' the fire box between said wall ends and fire bag.

In testimony whereof I affix my signature, in the presence of two witnesses.
